Frequently Asked Questions
What does a high SERP Volatility Index mean?
A high SERP Volatility Index (7.0 to 10.0) indicates widespread rank turbulence across search engine results pages. This is usually triggered by active unconfirmed Google Core Updates, Helpful Content recalibrations, or major AI Overview format tests.
What should you do if your site loses traffic during high volatility?
Avoid panic sitewide changes or mass URL redirects during active rollouts. Wait until algorithm volatility settles back below 6.0, audit Google Search Console impressions to identify affected query clusters, and inspect top-ranking competitors for format differences.
What is the daily usage limit for the SERP Volatility Checker?
